Why the appliances don't rate with the same current? What could be the reasons?
Answers
Answer:
But the current varies. The current changes to match the power needs. Only the voltage from the outlet stays the same. Current coming out of a typical Canadian or US domestic outlet is anywhere from a few miliamps to 15 amps. This is because of the appliances load or resistance. The more resistance the load the more power you need to overcome the resistance. Power = Voltage x Amps.
High powered appliances like air conditioners and small portable stoves have high wattage so they suck up a lot of amps. In the meantime your smart phone battery charger is only giving a few hundred milliwatts to charge up the battery in the phone and that means only a few dozen milliampst. These milli prefix means it’s 1/1000th of an amp and is very small.
